Applied Mathematics Seminars: Theory of Magnetic Reconnection in Solar and Astrophysical Plasmas
24 February 2017 14:00 in CM219
Magnetic reconnection is a fundamental process in a plasma that facilitates the release of energy stored in the magnetic field by permitting a change in the magnetic topology. In this talk, I will start by reviewing the mathematical background, in order to motivate the study of the reconnection process. I will then discuss the current state of understanding of magnetic reconnection, focussing on mathematical modelling in the continuum limit using the framework of magnetohydrodynamics. I will further discuss how analysis of the topological structure of the magnetic field can give clues as to possible locations of explosive energy release in astrophysical plasmas.

This seminar series is the continuation of the Numerical Analysis Seminar series that ran until August 2016. This change of name reflects the broader interests of the Applied Mathematics group (note that the Mathematical and Theoretical Particle Physics group also has a seminar series).
